Around 8:30 p.m. July 22, Bryan Muldoon was throwing rocks at an undisclosed home in unincorporated Boca Raton, causing more than $400 in damage to the window, according to the woman inside. After she called police, she called an unidentified 15-year-old, who she told deputies is Muldoon’s best friend.

Muldoon, of Fort Lauderdale, and the teen fought until Muldoon got on top and began stabbing him, according to the report.

Witnesses said the teen screamed out, “He is stabbing me!”

After the teen was able to get up, Muldoon and the woman who initially called 911 tried to help the teen with his wounds.

Though Muldoon told deputies he used a rock to injure the teen, witnesses not only said they saw a knife, they put the bloody weapon aside for authorities, according to the report.

Though it’s not mentioned in the arrest report, the two men told deputies that they were MMA fighters, according to PBSO.

Muldoon faces charges of aggravated battery and property damage. As of Thursday afternoon, Muldoon remains in the Palm Beach County jail on $54,500 bond.

Muldoon does not appear to have any previous arrests in Palm Beach or Broward counties.
